Mathias Färm (born September 9, 1974, in Örebro, Sweden) is a guitar player, best known as a member of the Swedish skate punk band Millencolin. He is also the frontman of a punk band named Franky Lee, a side-project of Millencolin.

He was the inaugural drummer for Millencolin but soon switched to guitar when Millencolin's current drummer Fredrik Larzon joined the band in 1993. This change was made because most of Millencolin's songs required two guitars on stage to duplicate the studio recorded sounds. Färm was also a more proficient guitarist than drummer. Currently, he lives in Örebro, Sweden. He's a vegetarian.[1] Mathias plays most rhythm guitars in the first albums three of Millencolin, but in the more recent albums, he performs most of the lead guitars, notably octave-style riffs and some solos.
